General Motors CEO Mary Barra gave investors a detailed playbook for the automaker’s future electric vehicles plans Wednesday, including a possible glimpse at a crossover based on the Bolt EV.

Barra gave the presentation for investors at the Barclays 2017 Global Automotive Conference in New York.

A picture of a possible Bolt EV-based crossover was included in the presentation. A spokesman for GM said the picture was a “demonstration of an all-new CUV segment,” but not necessarily a new product. The image lacks badges, but offers some new GM design elements such as rear roof pillars similar to those of the new GMC Terrain. A Bolt EV-based Buick Encore has been rumored, but not yet confirmed.

A small crossover may be unveiled next January at the 2018 North American International Auto Show in Detroit. A spokesman for GM confirmed that the automaker would sell four new electric vehicles by 2020, but didn’t say when those cars would be revealed.

Barra shared the automaker’s longer-term strategy for EVs, including autonomous ride-sharing services. In the presentation, she outlined plans for GM’s electric-vehicle platform that will eventually include five SUVs, including two luxury SUVs; two crossovers with one luxury version; two cars, including one luxury car; a commercial van; and a shared self-driving, ride-sharing vehicle. Barra said vehicles from the new platform would arrive around 2021.
